Abstract

This invention relates to cable test device and its scan method, wherein the device comprises the following parts: one MCU unit, communication connection unit, display unit and input unit to get human and machine order and to read reference cable information and to read cable information and to compare information and display the result; memory unit to store the test program and middle temporary data for MCU unit; interface buffer unit to provide test signal and cable matching unit buffer to provide several cable interface to send the signal to the cable interface and to get test signal from other end to form one ring test linkage together with the cable to be tested.

Description

technical field [0001] The invention relates to the field of signal connection testing in electronic and communication systems, specifically, a cable testing device and a scanning method thereof for production testing and on-site maintenance testing of various conventional cables. Background technique [0002] In electronic and communication systems, there are many cables used for signal connection. For example, computers contain parallel cables, power line cables and other cables; for many communication devices, cables are also an essential part. With so many different types of cables, how to use a fast and effective way to test whether their production is qualified is a basic requirement for mass production and testing, and it is also a requirement for rapid on-site fault diagnosis. [0003] In the Chinese patent "Cable Tester" with the patent No. 99245623.1, it is mentioned to use the method of comparative test for cable measurement, which is to use a good cable to test a...
